SEAL-LOCK.

.SPECIFICATION forming part of Letters Patent No. 253,388, datedFebruary 7, 1882. Application filed August 31, 1881. (No model.)

To all lwhom it may concern:

Be it known that I, FRANCISCO P. IANNA- RQNE, a citizen of the UnitedStates, residing at Washington city, District ot'Columbia, have inventednew and useful Improvements in Packing-Boxes, of which the following,lris a specification.

My invention relates to certain new and useful improvements inpacking-boxes, and more particularly to that class 'known and used ascoii or shipping boxes. y

The object ot' my invention is to obtain positive security againstaccidental or fraudulent My invention further consists in the details ofconstruction hereinafter fully set forth and specifically claimed.

In order thatothers skilled in the art may know how to make and use myinvention, I

will proceed to describe the construction and` operation of the same,referring by letters to the accompanying drawings, in which- Figure l isa bottom plan view of the lid or cover of my improved box, showing athreebolt lock and independent catch-bar. Fig. 2 is a centrallongitudinal and vertical section through a boxembodying myinvention.Fig.3 represen ts a bottom view of the covering-plate which conceals thekey-entrance to the lock proper. Fig. 4 is a plan or top view of thecentral cap-plate of the lock with the coveringplate removed. Fig. 5- isa plan view ot' the lock, exposing the bolts and bolt-operatingmechanism. Fig. 6 is a central section taken horizontally through Fig.5. Fig. 7 is a side or edge view ofthe cap-plate shown at Fig. 4; andFig. 8 is a section taken at line a: w, Fig. 4..

Similar letters indicate like parts in the several figures.

A represents la rectangular wooden box., which preferably has arrangedcentrally and at right angles to each other two countersunkstrengthening iron bands, BB, near the upper ends of which are providedboltholes or openings, through which theloclebolts pass. These bands aresecured by screws C, and hold the sides, bottom, and ends of the boxsecurely in place. D is the top, which israbbcted around the edges topermit the lock-bolts to move in aplane below the top edges ofthe boxandguard them against attack from the outside.

At the center otl the cover or top of the box, on the inside,is arrangedthelock-case E, which is secured in place by screws F, or in any othersuitable manner.

The lock shown consists of three radiating bolts, the inner ends ofwhich are provided with rack-teeth mes-hing with a centrally-arrangedpinion adapted to be operated by an ordinary key.

The top of the box is mortised or cut away over said lock to receive thehub G of capplate H, through which pass two or more screws, I', thethreads of which pass into the top plate ofthe lock-case E, and thushold the cap-plate in position. This cap-plate is provided with akey-hole, J, to permit the pas sage of the key tov the lock below; andit is furnished also with another key-hole, K, arranged within which isa post, L, secured to a bracket, M, on the under side of the plate.

N and O are two rectangular openings in 'said plate to receive hookssecured to the under side ot' a guard-plate presently' described.

Arranged underneath the opening N is a spring-latch, P, and in line withand slightly behind the opening O is arranged a ilat spring, Q, one endriveted to the under side of plate, F, and the other provided with astud, R,'which passes through an orifice in the plate H, and in itsnormal position projects slightly above the same.

On each side ofthe key-hole K are arranged two or more sharpened studsor points, S, adapted to pierce and hold stationary a paper or otherpuncturable seal.

The cap-plate is formed with an annular rim, T, which is designed tocome flush with the top of the box and high enough to receive within IOCit a guard-plate, U, having a key-hole, V, corresponding with thekey-hole K in the capplate, and two hooks, a b. Each side of thekey-hole, V, are two depressions, c c, adapted 5to receive the points SS. The plate Uis placed in position by passing the hook a through theopening O and under the plate H, and then, by pressing on the oppositeside of the guard-plate, forcing the beveled hook b under thespring-latch P. The key-holes K V are arranged to one side ot' thespring-latch I), and the latter is adapted to be operated by a suitablekey. Before placing the guardplate in position a paper or othereasily-punct. ured seal is placed over the hole K, and the points S Scaused to penetrate and hold the same against lateral movement, so thatwhen the plate U is latched in place it cannot be removed except by thewithdrawal ot' the latch by a key, the entrance ot' which must destroythe seal.

The seals used may bc in triplicateone furnished with the bill ot'lading, one placed under the guard-plate, and one kept with the stub orinclosed in the box; but in this particular any predetermined system maybe adopted.

To remove the guard-plate a key is forced through the seal under thekey-hole V, and by turning the key the spring-latch P is Withdrawn fromthe hook b, and when the hook is released the spring-stud R forces theplate upward sufficiently far for it to be grasped to withdraw the hooka, from its seat, when the plate may be entirely removed, thuseXposiugdthe cap-plate over the lock, and through which cap-plate the lock maybe operated.

The box may or may not be furnished with any suitable grasps or handles.

I do not Wish to confine myself to any special feature of constructionin the lock proper or the number of bolts used, as any character of lockmechanism may be used, the gist of my invention in this particularresting in the idea of providing the lock with acap-plate, access towhich is obtained only by the removal of a guard-plate.

What I claim as new, and by Letters Patent, is-

1. In combination with the lock secured on the under side ot' the lid ofthe box, and a capplate having a key-hole through Which thelockoperating key is passed, a concealing guardplate,U, provided with akey-hole, V, o'ut ot' register with the key-hole of the lock and adaptedto receive a diierent key, so that the guard-plate must be unlocked andremoved before access can be had to the key-hole of the lock,substantially as hereinbet'ore set forth.

2. In combination with the plate H, provided with openings N O and latchl?, and the guardplate U, provided with hooks a b, the springstud R,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand and seal in thepresence ot' two subscribing witnesses.

desire to secure F. P. IANNARONE. [L s.|
